The length of the penis can decrease by up to an inch or so for various reasons. Usually, changes to penis size are smaller than an inch. Although a slightly shorter penis will not affect your ability to have an active satisfying sex life it may reduce your sexual confidence.
Causes of Penis Shrinkage
As you get older, your penis and testicles may get slightly smaller. One reason is the buildup of fatty deposits in your arteries reducing blood flow to your penis. This can cause withering of the muscle cells in the spongy tubes of erectile tissue inside your penis. The erectile tissue are engorged with blood to produce erections.
Over time, scarring from repeated small injuries to your penis during sex or sports activities can cause scar tissues to build up. This occurs in the formerly supple and elastic sheath that surrounds the spongy erectile tissues in your penis. This could reduce the overall size and limit the size of erections.
If you gain weight, particularly around your lower abdomen, your penis may start to look shorter. That is because the thick pad of fat starts to envelop the shaft of your penis. When you look down at it, your penis may seem to have gotten smaller, in extremely obese men fat can enclose most of the penis.
Up to 70% of men experience mild to moderate shortening of their penis after having a cancerous prostate gland removed. This procedure is called radical prostatectomy.
Expert are not sure why the penis shortens after prostatectomy, one possible cause is abdominal muscle contraction in a man’s groin that pull the penis farther into their body.
Difficulty getting erection after surgery starves the erectile tissue of oxygen, which shrinks muscles cells in the spongy erectile tissue. Less stretchy scar tissue forms around the erectile tissue.
If you experience shortening after prostate surgery, the usual range is ½ to ¾ of an inch, as measured when the penis is stretched out while flaccid or not erect. Some men experience no shortening or only a small amount. Others experience more shortening than average.
Peyronie’s disease (curving of the penis)
In peyronie’s diseases, the penis develops an extreme curvature that makes intercourse painful or impossible. It can reduce the length and girth of your penis. Surgery to remove the scar tissue that causes peyronie’s can also reduce the size of the penis.
Other causes of penis shrinkage include excessive masturbation, smoking and alcohol intake.
Treatments and Prevention
Erectile function can be maintained with aging by remaining physically active, eating a nutritious diet, not smoking and avoiding the consumption of excessive amounts of alcohol. Maintaining erectile function is important because erection fill the penis with oxygen-rich blood, which nourishes the penis and inhibit shortening
If your penis shortens after prostate removal, you should be patient and wait. In many cases, shortening will reverse within 6 to 12 months after surgery. Doctors might suggest penile rehabilitation as treatment.
Penis shrinkage from peyronie’s cannot be reversed. Your main concern will be reducing the curvature to restore sex life.
